BP650-45 Bandpass Filter(CWL=650nm,FWHM=45nm)

The BP650-45 is a precision bandpass filter engineered for high-performance fluorescence imaging and spectroscopy applications requiring moderate spectral isolation at 650 nm in the red spectrum.

Key Specifications:

• Center Wavelength (CWL): 650 nm
• Full Width at Half Maximum (FWHM): 45 nm
• Optical Density (OD): >6 blocking
• Transmission: High-efficiency dielectric coating
• Substrate: Precision-grade optical glass

Applications:

• Red fluorescence microscopy and multi-channel imaging
• Broadband signal detection and imaging
• Flow cytometry and cell sorting systems
• Confocal microscopy and widefield imaging
• Spectroscopy and optical sensing applications

Performance Features:

• Moderate 45 nm bandwidth for balanced spectral selectivity and signal throughput
• OD >6 out-of-band blocking eliminates crosstalk and background noise
• Hard dielectric coatings ensure long-term stability and durability
• Optimized for integration into fluorescence filter cubes and optical assemblies
• Ideal for applications requiring broader spectral coverage in the red spectrum

Each filter is individually tested and verified to meet published spectral specifications. Transmission curves and test data available upon request.
